I am testing loop behaviour in 2.4.3 and 3.4.4p3. I have noticed something
disturbing:

I can mount the same file on the same mountpoint more than once. If I
mount a file twice (same file on the same mount point)
both mounts (identical) show when I do df or cat /proc/mounts. If I issue
unmount (once), both mounts disappear from df output, but one of them
remains in /proc/mounts. If I issue umount again, the second mount
disappers from cat /proc/mounts output, but the module 'loop' shows as
busy and cannot be removed even though there are no more loop mounts.
lsmod shows loop being used by 1 process.
If I repeat this whole procedure again, loop will be used by 2 processess
in the end. I guess something is wrong here.
This experiment has been done under 2.4.4pre3. I will try the same under
2.4.3.

cheers,
